Description
Technical field
The present invention relates to grinding test technical field, in particular to a kind of grinding test device based on angle grinder.
Background technique
Emery disc is that the common consumptive material of workpiece polishing grinding is typically mounted in angle grinder and is used in grinding field；Angle
Grinding machine generally comprises head and handle, and angle grinder generally can also open up two threaded holes using as auxiliary in the two sides at head position
The mounting hole of assistant's handle, installation assist handle is that personnel grip angle grinder for ease of operation.
Emery disc needs to test its grinding performance in R&D process, usually emery disc is mounted in angle grinder to test,
But since operator holds when angle grinder polishes to workpiece it is difficult to ensure that the active force that emery disc acts on workpiece is
One constant force, at the same time it is difficult to ensure angle grinder keeps an invariable grinding angle, and emery disc acts on workpiece
Active force and angle grinder grinding angle be influence emery disc ground effect key factor, so this results in operator's hand
The validity of the test data obtained when holding angle grinder test emery disc grinding performance is lower.
Summary of the invention
